Abstract
A number of domestic audio/video apparatuses (10,12,14) are interconnected by a Domestic Digital Bus (16) for the exchange of control information. A User I/O subdevice (41) in one apparatus is addressable by a control subdevice (22) of another apparatus to allow the display of menu items defined by the control subdevice. The User I/O subdevice returns user control signals by reference to the defined menu items. The right of menu control can be transferred via the User I/O subdevice to and from other control subdevices (20 etc.) to allow integration of the menu control functions of the different apparatuses.
